No, because it's $200 on top of what you would otherwise spend on the stuff you buy. The cost of marketing has to get baked into the price of goods or the sellers would be losing money. If they weren't advertising, or could advertise for less, they'd be able to lower prices.

Advertising can lower the cost per item, if there was a large startup cost and marginal costs are small. More importantly, facebook ads have caused me to buy more things because the ads showed me things that I thought were useful that I otherwise wouldn't have known about. Honestly, I feel like maybe I should be paying to see FBs ads sometimes.
